摘　　要：目的探讨高频超声在鉴别儿童回结肠型与小肠型肠套叠中的价值。方法回顾性分析我院103例回结肠型肠套叠患儿和52例小肠型肠套叠患儿的影像学资料,并比较其声像图特征。结果 103例回结肠型肠套叠的套头部平均直径(3.08±0.35)cm,平均脂核厚度(1.42±0.36)cm,外层肠壁厚度(0.60±0.13)cm,核-壁指数均>1,套筒内含淋巴结92例(89.3%);52例小肠型肠套叠的套头部平均直径(1.78±0.39)cm,平均脂核厚度(0.10±0.24)cm,外层肠壁厚度(0.41±0.11)cm,核-壁指数均<1,套筒内淋巴结7例(13.5%),二者肠套叠直径、脂核厚度、外层肠壁厚度、核-壁指数、套筒内有无淋巴结比较差异均有统计学意义(均P<0.01)。结论高频超声在鉴别儿童回结肠型与小肠型肠套叠中有重要价值。Objective To evaluate the value of high-frequency ultrasound in differential diagnosis of ileocolonic and small intestine intussusception in children.Methods The imaging data of 103 cases of ileocolon intussusception and 52 cases of intestinal intussusception were analyzed retrospectively,and the sonographic features were compared.Results In 103 cases of ileocolon intussusception,the average diameter of head was(3.08±0.35)cm,and the mean lipid-nucleus thickness was(1.42±0.36)cm,the thickness of outer intestinal wall was(0.60±0.13)cm,the nuclear-wall index was>1,and 92 cases(89.3%)contained lymph nodes in the sleeve.In 52 cases of small intestine intussusception,the mean diameter of head was(1.78±0.39)cm,and the mean thickness of lipid nucleus was(0.10±0.24)cm,the thickness of outer intestinal wall was(0.41±0.11)cm,the nuclear-wall index was<1,and 7 cases(13.5%)contained lymph nodes in the sleeve.There were significant differences of intussusception diameter,lipid nucleus thickness,thickness of the outer intestinal wall,nuclear-wall index,and lymph nodes in the sleeve between the two groups(all P<0.01).Conclusion High frequency ultrasound has important value in differential diagnosis of ileocolonic and small intestine intussusception in children.
